Because that's literally how they fund their entire society? Even with the super high taxes, it's not enough to cover the level of social spending they are trying to maintain. Not to mention that it's also going into a fund for all pensions. In that way, it's great that the government kept control over the fossil fuels and that the money from them at least serves the Norwegian people.

Right, so practical reasons and sovereignty trump environmental consequences. This standard should be applied for all countries.

Because this (or other) fuel is still necessary right now. The way they use the money also benefits the whole country. Cutting down the Amazon is not necessary and merely benefits a small number of farmers.

Also Norway is taking steps to moving away from an oil based economy.

The comparison is invalid. This isn’t about ending existing means of supporting Brazilian society. These are about new measures that will (a) damage the rain forests, (b) almost certainly negatively impact ordinary Brazilians, and only enrich a few well connected folks.

The idea that killing the goose kind of growth will help ordinary citizens has shown to be false time and again in nearly every other nation.

What about the rest of the world? Does Norway’s fossil fuel extraction do any good for the world?

What kind of question is that? What is your intention, I mean?
